Question:
A viscously damped spring-mass system is excited by a harmonic force of constant amplitude F0 but varying frequency w. If the amplitude of the steady-state motion is observed to decrease by a factor of 8 as the frequency ratio w/wn is varied from 1 to 2, determine the damping ratio ζ of the system.
